Answer:
The answer to the math problem is 215 1/3,
but what the question posed means I'm not sure.
You can check this quotient by:
3*215 + 1 = 646
Step-by-step explanation:
Given that the sides of the acute triangle are as follows:
21 cm
x cm
2x cm
Stated that 21 cm is one of the shorter sides of the triangle2x is greater than x, so it follows that 2x MUST be the longest side
For acute triangles, the longest side must be less than the sum of the 2 shorter sides
Therefore, 2x < x + 21cm
2x – x < 21cm
x < 21cm
If x < 21cm, then 2x < 42cm
Therefore, the longest possible length for the longest side is 42cm
You can each order from: Column A- 6 times, Column B- 4 times
3 pipes take 12 hours
⇒ In 1 hour, the 3 pipes can fill 1/12 of the pool
2 of the pipes take 18 hours
⇒ in 1 hour, the 2 pipes can fill 1/18 of the pool
In 1 hour, the third pipe alone can fill :

Time needed :

Answer: It will take 36 hours for the third pipe to fill the pool.----------------------------------------------------------------------------------------
Your answer should be:
(10-6)x(2+8)=40
